Whether other sins dissolve marriage?

❌ Objection 1 : It would seem that other sins besides unbelief dissolve marriage. For adultery is seemingly more directly opposed to marriage than unbelief is. But unbelief dissolves marriage in a certain case so that it is lawful to marry again. Therefore adultery has the same effect.

❌ Objection 2 : Further, just as unbelief is spiritual fornication, so is any kind of sin. If, then unbelief dissolves marriage because it is spiritual fornication, for the same reason any kind of sin will dissolve marriage.

❌ Objection 3 : Further, it is said (Mt. 5:30): "If thy right hand scandalize thee, pluck it off and cast it from thee," and a gloss of Jerome says that "by the hand and the right eye we may understand our brother, wife, relatives and children." Now these become obstacles to us by any kind of sin. Therefore marriage can be dissolved on account of any kind of sin.

❌ Objection 4 : Further, covetousness is idolatry according to Eph. 5:5. Now a wife may be put away on account of idolatry. Therefore in like manner she can be put away on account of covetousness, as also on account of other sins graver than covetousness.

❌ Objection 5 : Further, the Master says this expressly (Sent. iv, D, 30).
